ROBERT G. JENNINGS, OF ELMIRA, NEW YORK.

YARN -GLEANER.

Application filed September 22, 1911.

To all whom it may concern Be it known that I, honnn'r G. JENNINGS, a citizen of the United States, and a resident of Elmira, county of Chemung, and State of New York, have invented certain new and useful Improvements in Yarn-Cleaners, of which the following is a specification.

My invention relates to devices for removing impurities such as broken seeds, fragments of leaves and stalks, dirt, burs, lumps of fiber and the like, such as are found in cotton and other yarns after passing through the usual manufacturing operations, and embodies modifications of devices for similar purposes previously described and patented to me in the United States, May 9, 1911, No. 991,510.

The object of my present invention, as of the invention of my earlier patent just referred to, is, broadly speaking, to provide effective means for separating such impurities from the yarn preparatory to the Weaving and knitting operations.

A particular object of my present invention is to provide devices of the same general character and operating on the same general principle as the invention of my earlier patent, but with less tension upon the yarn, and of simplified and more compact form. A further object of my present invention is to provide an automatic adjustment in devices of the character specified by means of which yarn of any diameter may be operated upon without change of parts or manual adjustment requiring attention and involving loss of time. A further object of my invention is to provide means for instantly arresting all moving parts of the yarn cleaner upon breakage of the yarn. A still further object of the present invention is to provide devices of the character specified, such that the yarn may be more readily applied to said devices in the first instance, or in case the yarn should break during the cleaning operation; other incidental objects will appear as the specification proceeds.

The invention also comprises improved means for removing and massing together,

in a substantially continuous manner, the n'npurities as they are removed and collected from the yarn.

In my prior Patent, No. 991,510, above referred to, I have described and claimed a yarn cleaning device comprising a bed or bracket over which the yarn is drawn parallel to and immediately beneath a pair of Vd gripping edges, means being provided for twisting the yarn, if necessary, as it approaches said edges, so as to cause any attached impurities, specks of dirt, etc, to enter the V formed by and between said edges and to be caught and held there while the yarn is then drawn aside from its direction of travel over the bed, so as to detach it from said impurities, which are left behind between the gripping edges. Each pair of gripping edges with the immediately associated parts as the bed, means for twisting the yarn, etc, may be termed a cleaning unit. Since, in operation, the yarn is caused to travel at a high rate of speed and since an occasional speck or other impurity may slip through the cleaning unit without being detached, I prefer to employ several cleaning units placed so that the yarn to be cleaned will pass through them successively, (four are shown in the specification referred to). But since to detach a speck, the yarn must be turned in direction so as to be led away from the gripping edges, while to pass through the next cleaning unit the yarn must )e brought back toward its previous line of travel and be again led over the bed adjacent to the gripping edges of said next unit, the tension upon the yarn in drawing it through the apparatus is very materially increased over and above that which would exist were the yarn drawn through the apparatus in an unvarying straight line and, correspondingly, the liability to breakage is also increased. Furthermore, in positioning the yarn, in the first instance, in the ap aratus preparatory to cleaning it, as also a er a break has taken place, a very considerable time, as well as degree of operative skill, is required to wind the yarn back and forth Patented Apr. 22, 1919? through the various cleaning units and over the various ii'itermediate pulleys or other means which may be employed for changing the direction of travel of the yarn.

My improved apparatus, as set forth in the present specification, avoids these-objections as well as presents certain other advantages.

Essentially my present invention consists in replacing the bracket or bed 3 of my earlier patent by a bed curved forwardly and away from the line of travel of the yarn and by causing the gripping blades 4 and 5 of said patent to be turned intoplanes normal to the surface of said bed instead 0 parallel thereto, the blades being placed back to back, with their edges forming Vs with the curved bed, and with each edge conforming generally to the curvature of the bed. In this way the bed itself becomes a common gripping edge or blade with relation to each of the two remaining blades proper. (Jonsidered from another point of view each blade proper becomes a begl with relation to the remaining blade and the curved bed taken as a pair of gripping edges. The curved bed and the blades lead the removed impurities away from the initial line of travel of the yarn and said yarn may, therefore, be drawn through each and every cleaning unit along one and the same straight line, thereby eliminatin'gthe tension due to the frequent change of direction in the apparatus of my earlier patent. As will be seen later, this construction also greatly facilitates placing the yarn, in position in the apparatus, either initially or after a break has taken place.

In the accompanying drawings, which are hereby made a. part of this specification, Figure 1 represents aside elevation and Fig. 2 a plan iew, of-a. preferred form ofmy invention Fig. 3is a side elevation, considerably enlarged, of one of the cleaning units shown in Figs. 1 and 2; Fig. 4 is a transverse section, similarly enlarged, taken along the line of F1 ;1; Fl 5 ise side elevaitionofamodifie form 0- my invention ve similar to the form shown in the precedin figures, save that the cleaning units are a tiernetely 15813 in two planes d gfi'ering b 90;Fig-.;6 ise. side elevation and Fig. 7 a planview of another modification of my inventiomfig.

referring to :the form shown in Figs. 1 to 4,9. rectangular supporting bar 1 carries four cleaning units 2, 2, spaced along its length and is-provided on its rear end, to the left of said units, with a tension device 3 of conventional form beneath which is supported an open circular wire loop or eye 4.

Each cleaning unit comprises a bracket or bed 5, fixed to the bar 1, having an upper surface which is flat for a short distance and is then curved forwardly and down wardly in sickleshapedoutline; and a. pair of gri pi blades 6,6 ivoted upon one side 0 the ar, on a spn'idle 7, at the left and beneath the rocket, transverse to the bar. Each ofthese blades is also sickle shapedand hasits inner edge beveled on its outer side and ill-0011M with the bed 5 at the forward end thereof while diverging gradually therefrom toward the pivoted end of the blade so 138 to leave a curved V 'slot between saidbladeand said bed. Theends of the-blades areprolenged in their downward curve 'andterminate well below the bed 5. The pair of blades is kept premed together, backtoback, by a coiled s ring 8 mounted upon the axis, and each lade is provided with. ears 9, flaring awayfrom one another, and-outwardly expanded portions below saidearsconstituting a. clearance 10 who'smaxisis substantially coincident with the adjacent up eredge 10of bed 5.

The bottom 0 bed 5 is slotted longitudi nallyso as to fi tdown over bar 1 and the screw 5 which holds said bed to said bar passes through a hole in the bar which is somewhat larger than the shank of the screw (see Figs. 3 and 4) so that the bed has a certain sliding adjustment lengthwise of the bar thus permitting a corresponding variation in the exact character of the curved V s ot.

Beneath the bed and projecting from each blade 6 to the right of the pivot is an arm 11, the outer end of which lies normally a little above and spaced from the end of a cylindrical pin 12, rotatably fixed in the bar 1; the end of thls pin is cut away on its upper side down to its central lane and it is upon the flat surface thus established that the arm 11 rests. The other end of pin 12 is bent, parallel with and adjacent to the side of bar 1 remote from the blades 6, to constitute a trip-arm 13.

Fixed to the bar 1 below the arm 11, is an adjustable screw 14 adapted to clamp a rotatable adjustable lug 15, to which is attached a coiled tension spring 16 linked to a ring or yoke 15 which embraces both arms 11 of the particular cleansing unit whereby a constant downward pressure is exerted thereupon to keep the blade edges against the bed. Each blade of a given cleaning unit is, hence, adapted to yield independently of its companion blade so as to positively grasp and hold the impurities which may be drawn under its edge.

Supported upon the right of bar 1 with its bottom groove in line with the flattened portion of the top of the beds 5 is a grooved pulley 17. A guard wire 18 is rotatably attached to the bar by a straight portion 19 and may be swung up at the side of the pulley or down away from the pulley (dotted lines Fig. 1) as may be preferred.

Upon the side of bar 1, opposite the blades 6, and extending longitudinally of said bar is supported a tripping shaft 20 having at one end a gear 21, meshing with a worm 22. Projecting normally from this shaft and corresponding to each cleaning unit is a pin 23, each pin being set in a plane 90 in advance of that of the preceding pin. The worm 22 is fixed upon a spindle carrying a pulle 24, adapted to be rotated by a light belt not shown) taken from any convenient source.

The edge of the outer blade 6 (the blade remote from the bar 1) as it diverges from the bed 5 is shorter on its rear end than the corresponding edge of its inner companion blade, being cut away at 25. The corner 26 of the inner blade corresponding to this cut away portion of the outer blade 6' is bent slightl toward the lane of said outer blade, (see igs. 3 and t and constitutes a dcfiector to turn the speck 27, which is to be removed, into a favorable position to be caught by the gripping edges. This particular arrangement is preferred when right hand twist yarn is being cleaned. In the case of left hand twist yarn the reverse arrangement should preferably be employed z'. e. the outer blade should be the longer and be provided with the deflector while the inner blade should be cut away.

The operation of my invention as just described is as follows: The yarn 28 is passed up through the eye 4 and through and between the disks of the tension device 3, and is then laid along and between the ears 9 of the gripping blades and in the groove under the pulley 17, being thence run off in an upward direction to the winding machine. This will cause the yarn to lie lightly along the upper flat surfaces of the beds 5, being pressed between the blades 6, 6 and passing axially through the guides 10.

As the yarn is driven through the apparatus at a very rapid rate of speed, each speck 27 as it contacts with the edge 10' of the bed will be turned by said edge to project above the bed to be either instantly met by the corner or deflector 26 which will turn the speck either to the left or right, so as to slip into one or the other of the two V slots formed between the two blade edges and the bed, or else to slip naturally into one of said slots without being met by said deflector. As the yarn passes through the several cleaning units and over the pulley 17 it will lie in one and the same straight line and will contact with the edge 10 of each bed The yarn will be lightly held between and against the inner sides of the two blades 6, G of each cleaning unit through the pressure of spring 8, and these blades will yield to and conform with any variation of diameter of the yarn as it is drawn along. Hence, the blades will adjust themselves automatically to receive and operate with yarn of any diameter which may require to be cleaned.

After the specks have entered and been gripped in the V slot between one or the other blades and its bed, they are drawn forward by the yarn into the narrower region of the slot where they are left by the yarn as the latter is eventually pulled away from them. Each successive particle will push the preceding speck a little farther along and into the downward curve of the slot, and the tendency of these removed particles is, therefore, to mass or bunch together and eventually to cause the earlier removed particles to pass completely along and through the slot and out over the forward end of the bed 5. Since to thus push the mass of removed particles through the slot puts an extra strain upon the yarn and since, further, the mass of particles tends to raise the blades and unduly widen the slots, it is desirable to assist, if possible, the movement of the massed particles and to free them from the cleeningilmit before they become too numerous. atcflmplisl this through the rotation of the shaft 20 fromthe pulley 24; esthe shaft: revolvesthe pins 23 successively centnctwith and raise the trip-arms 13 through a-sniall engle ithns correspondingly turning the ,pins 12 rand raising the blades 6, 6 hylmeens of the fiet of the pins 1.2 and the arms 11. Thesprings 16 will restore'the blades to their eriginql contact position with the beds so seen as the pins 23 have passed the trip-urine 13 each pair of blades is thus raisedviorthei in? stant the ,rcssure upon the massed pet ifiies is release and the entire mass moves fol? Ward tow ard the forward end of the! bed.

The purpose of using more than one cleaning unit is to insure that the yarn-shell be thoroughly cleaned; any particle-which may happen to beheld by the yarn especially tightly and hence may he only partially detached by the first cleaningunit or which i r any reason may slip by the first cleaning unit altogether has still topess through the remaining units and is certain to bereinovecl before the yarn emerges from "the last of said units.

The modification-shown in Fig, 5 is new similar to that of Figs, l to 4 just described, except that the component parts of each 7 cleaning unit are successively and alternately mounted upon adjacent sides ofthe square bar 1, The blades 6 and beds 5 of the several cleaning units are so setthat when the yarn lies in position between the blades and upon the brackets, said thread will be perfectly straight. In this form of my device the cleaning units have been turned eat right angles to one another to avoid the use of the inwardly projecting tongue or deflector 26 of the form above described. A

speck which slips through the first cleaning unit because parallel to its planes is chriously in the best position to be gripped by the blades of the next cleaning unit.

The modificationshown in Figs, 6 and 7, more nearly resembles that of Figs. 1 to 4 than it does the form shown in Fig. 5. Save for the feet that the exact curvature of the sickleshaped gripping edges of the :blades 6 6 as well as the contour of the upper surface of the bed 5 differs some What, the only essential difference is the supporting of the bed upon a pivot 29=snd the use 0 a link 80 attached to each had and connected with a slidable side barl having a lug .32, sdaptcclito contantedand pressed upon by some suitable operative element. The bar is restorted to it initial position byte quick return spring 33. This :arrangement permits the beds 5 to he shiited under the blades in periodic fashion and assists in freeing the slots between heds andrblade'edges from the messed particles collected from the yarn. llhe one blade 6 raising has its e rnsr 2t ti ned u der eth r lade tceeeshtete s deflseto -es in he treeture; shown in iEips, '1 toe.

Referring to the figures the wire from which the trip arm 13 is bent up is light and springy, being preferably a piece of piano wire. The trip arm itself has an upwardly and rearwardly inclined loop 49 with a long terminal limb 50 which rests against or near to the outer periphery of the tripping shaft 20. The shorter arm of the loop IS bent to pass loosely and transversely through the supporting bar 1 and is then again bent to provide a forwardly extending square loop having a base portion 50' under but spaced from the arms 11 and a terminal limb 51 which extends upwardly and rearwardly so that its end rests normally against the under side of the bed 5. When the tripping shaft is rotated (in the direction of the arrows Fig. 16) each pin 23 engages the trip arm 13 and forces the end of limb 51 tightly against the under side of bed 5 springing both said limb and thetrip arm. As the pin 23 slips past the trip arm these spring por tions suddenly .react and the base portion 50 is thrown up against the arms 11 resulting in an efi'ective but exceedingly quick raising of the blade edges from the bed.

he supporting bar 1, which carries the cleaning units, is itself carried by a bracket 52 with which ithas frictional sliding clovetailed engagement (shown dotted at 53) this bracket itself being arranged for attachment to the winding or other machine with which my. yarn cleaner is to be associated. The cleaning mechanism proper may, therefore. for the purposes of inspection and repair be instantly and entirely disengaged from the bracket which carries the driving mechanism now to be described. Arranged parallel to bar 1 and passing slidabiy through thehead of this bracket is a shift spindle 54 the inner end of which is provided with a washer having an annular recess 55 While the outer end is slotted to slidably receive a shifting link comprising a wire bent at one end to provide a figure of wedge shaped contour 56, and at the other end to provide an arm 57.
